Croissant Steak Sandwiches With Caramelized Onions And Horseradish Mayonnaise Recipes

Steps:

• Mix mayonnaise and horseradish in small bowl to blend.
• Melt 1 tablespoon butter in heavy large skillet over medium-high heat. Sprinkle tenderloin steaks with salt and pepper. Add steaks to skillet and cook to desired doneness, about 5 minutes per side for medium-rare. Using tongs, transfer steaks to work surface.
• Melt 3 tablespoons butter in same skillet over medium-high heat. Add onions; sauté until dark brown, about 25 minutes. Add mushrooms; sauté until tender, about 5 minutes. Add broth; boil until juices are reduced to glaze, stirring occasionally, about 1 minute. Season onion mixture to taste with salt and pepper.
• Place 1 croissant bottom, cut side up, on each of 4 plates. Spread each with horseradish mayonnaise and top with 1/2 cup arugula. Thinly slice steaks and divide among croissants. Top with onion mixture. Spread remaining mayonnaise on cut side of croissant tops. Place tops on sandwiches.

Steps:

• Season the steaks with salt and pepper. In a medium skillet, melt the butter over medium-high heat. Cook the steaks for about 5 minutes each side for medium-rare. Set aside for 5 minutes before slicing. Slice the steak, across the grain, into 1/4 to 1/2-inch thick slices.
• Heat a large nonstick skillet or griddle over medium heat. Using a serrated knife, slice the croissants in half lengthwise. In 2 batches, place the croissant halves, cut side down in the skillet and cook for 30 seconds to 1 minute until lightly toasted. Lay the Brie slices over the toasted croissant halves. Place about 1/4 cup of the arugula on the bottom halves of the croissants. Add the sliced steak. Arrange the red bell pepper on top of the steak. Top with the remaining arugula and add the top of the croissant. Serve immediately.
